The private plane of U2 front man Bono lost a hatch on its approach to Berlin, authorities at the German airport have said.
There was no risk to the Irish singer in the incident.
Airport spokesman Ralf Kunkel told the DPA news agency that the 32in (80cm) by 40in (100cm) rear hatch landed in the vicinity of Schoenefeld airport, on the south-eastern edge of Berlin.
He said it was not clear why the hatch came off and that German authorities were investigating.
Mr Ralf said the aircraft, which was flying from Dublin, was never in danger of crashing and landed safely.
According to NBC News, the two pilots only found out on the ground that the aircraft had lost its door and two suitcases from the luggage compartment.
They told investigators that they noticed a rumble similar to turbulence during a right-hand turn on approach, but that they felt no major change in how the plane was flying.
Bono is in Berlin for the Bambi awards.
U2 frontman Bono has revealed the mystery behind his trademark sunglasses: glaucoma.
Bono told BBC's Graham Norton he had suffered from the condition for two decades.
"This is a good place to explain to people that I've had glaucoma for the last 20 years. I have good treatments and I am going to be fine," Bono said.
"You're not going to get this out of your head now and you will be saying 'Ah, poor old blind Bono'," the singer joked.
Glaucoma is a disease that damage the optic nerve of the eye, causing deterioration over time. In some cases, it can result in blindness.
Bono, 54, is known for almost always wearing shaded glasses in public, even indoors.
Asked about them in the past, he has said only that his eyes are sensitive to light.

Invisible will be made available on iTunes for 24 hours, with the Bank Of America donating 60p for each download, to a maximum of £1.2 million, to the Global Fund To Fight AIDs,Tuberculosis And Malaria.

Bill Clinton has responded to Bono's impersonation attempt with his own impression of the U2 singer.
Appearing on Piers Morgan's CNN talk show, Clinton pulled on a pair of dark glasses before trying out an Irish accent.
Earlier this week Bono delighted the crowd at a Clinton Global Initiative event with a striking impression of the former US president.
U2 singer Bono has been showing off his best American drawl as he impersonated for Bill Clinton.
As he waited for the former US president on stage at the Clinton Global Initiative in New York, Bono began a striking impersonation of Mr Clinton.
To the obvious delight of the audience the U2 frontman described how Clinton "thought he was one his roadies" the first time they met before listing their humanitarian achievements.
When Mr Clinton did arrive the Irish singer leapt back in to his own seat as the former president said he "must be really easy to make fun of."
Bono filled in for Bill Clinton at a meeting of heads of state and business leaders - by jumping into the former US President's chair and doing an impression of him.
